Mechanical

I have strong frequency-periodic noise in my measurement system. Is there a indexed notch filter where frequency content is filtered at multiples of a primary mode? [e.g. 100 hz, 200h z, 300 hz,.....]

I'd be interested in the math form of such a filter exists or a solution in either MathCAD, LabVIEW, or Excel...
